Hill's Prescription Diet Canine z/d is a unique combination feed, developed to aid dogs with numerous food allergies and intolerances, which can often lead to the onset of further health conditions such as digestive difficulties. Allergies and intolerances are typically an adverse response to food proteins, and Hill's Prescription Diet z/d has been specially formulated to counter-act these proteins and lower the risk of allergies arising from beef, wheat and dairy products.

Redness of skin

My dog has finished her steroids and anti biotic about a week ago. She has been on z/d for nearly three weeks. Her skin has started to go red again and has started to lick her paws again. Does this mean the allergy is not food related X

This is suspicious and it might rule out a food allergy, but it is too early to say. Some dogs do need more than 3 weeks to show a full response. Also some dogs will pinch a small amount of food (bread, biscuit etc) and if they happen to have a wheat allergy, or some other constituent of what they ate, they will react again. I would certainly suggest that you give the diet more time, but you are right and it might prove that this is not purely a dietary allergy. It is a bit too early to be sure about that.

My dog is allergic to potatoes corn wheat and rice has severe skin. Allergies tothese myvet has put him on hills zd he loves it.but notice this has potatoes in.

John Cousins BVSc MRCVS

All the proteins in Hills z/d have been treated to make sure that they are not recognised by the immune system. This means that even if potato is bad for your dog (which is unusual but certainly possible) it is OK to give him this particular food. [The proteins are "hydrolysed" which means they are broken down into smaller molecules. This does not affect their nutritional value, but makes them unable to cause an allergic response.]
